:: Please be aware that unencrypted e-mail, skype and/or phone calls are no secure ways of communication. Your communication can be easily accessed by

:: I therefore highly recommend to switch to encrypted communication, i.e. e-mail-encryption via PGP and/or open-sourced Signal-messenger [see below]. In
general I also recommend using Tor to reduce
your footprint while being online ::
